Electrostatics-induced breakdown of the integer quantum Hall effect in cavity QED
Gian Marcello Andolina, Zeno Bacciconi, Alberto Nardin +3
We address the prevailing theoretical explanation of the recently observed breakdown of the integer quantum Hall effect in a two-dimensional electron gas embedded in a metallic spl…

Plasmonic metamaterial time crystal
Tingwen Guo, Jules Sueiro, Gian Marcello Andolina +18
Periodically driven optical materials and metamaterials have recently emerged as a promising platform for realizing photonic time crystals (PTCs), which are systems whose optical p…

Floquet Theory of lattice electrons coupled to an off-resonant cavity
Jules Sueiro, Gian Marcello Andolina, Marco Schirò
We use Floquet theory and the High-Frequency expansion to derive an effective Hamiltonian for electrons coupled to an off resonant cavity mode, either in its vacuum or driven by cl…
